Together with their Munich-based colleagues, a team of physical chemists from Heinrich Heine University Düsseldorf (HHU) has clarified which chemical reactions take place during PUVA therapy. The therapy involves light-induced damage to the DNA of diseased cells. The team working under Prof. Dr. Peter Gilch has now published its findings in the Journal of the American Chemical Society.

It normally takes about 21 days for chicken embryos to develop into chicks. By observing chicken hindlimb formation, a CNRS / Université de Paris research team has just discovered that the mechanism at the origin of embryonic development consists of a sequence of reflexive contractions. The researchers were able to artificially recreate the same process and accelerate it by as much as a factor of 20.

Using ultrasonic tweezers, live imaging and a micro-mechanical substrate, NYU Tandon researchers found energy patterns in cellular allostasis that could predict the presence of disease.

DGIST Professor Jaeheung Cho in the Department of Emerging Materials Science secured materials that lead aldehyde deformylation reaction. Confirmed the nucleophilic reactions by biomimetic materials... Expects to bring positive impacts on related research.

A collaborative team at the Wyss Institute, Harvard SEAS, and the University of Nebraska Omaha reports in Science that they now have developed the first portable exosuit that can assist the extension of the hip joint during both walking and running. The team successfully tested their wearable robot in uneven outdoor environments while wearers walked uphill, and walked and ran at different speeds.

A soft robotic exosuit -- worn like a pair of shorts -- can make both walking and running easier for the wearer, a new study reports.

Voltage-gated ion channels at the surface of neurons and muscle cells control your every thought, movement; the very beating of your heart. For the first time, researchers at the EPFL's Blue Brain Project have mapped the behavior of the largest family of these channels. Published in Frontiers in Cellular Neuroscience, and freely available online as raw data, their pioneering work will power virtual drug discovery -- and, they hope, the first whole-brain simulation.

Capturing the motion of single molecules is achieved by a method known as fluorescence correlation spectroscopy (FCS). The catch? It takes many detections of light particles -- photons -- emitted by single molecules to get a clear picture of molecular motion.
